Question

Please help me use full explanation please hurry

Answer 1

Step-by-step explanation:

   As we can see the question given

    f(x) is varying accordingly to the interval

   f(x) = 2 if 2<x≤4

    The value of function is 2 for the interval 2 to 4

    and interval is open at x=2 and closed at x = 4

    f(x) = x + 3  if  4<x<8

     The value of function is x + 3 and it is open at x = 4 and x = 8

    f(x) = 2x if x $\geq$8

     The value of function is 2x for x greater than or equal to 8
